This invention relates to devices for physical exercise and pleasure,particularly for childrenvwhere large numbers of them are to beentertained in public parks and school and other playgrounds, and theobject of the invention is to provide a strong and durable structurecapable of being shipped in sections and assembled and erected byunskilled labor, and a further object is to provide a coaster-slide witha series of waves which will ailord a` corresponding number of thrillsto the person using it and finally leave them in an easy sitting postureon the lower end oi' the slide.

l accomplish the above, and other objects which ewill hereinafterappear, by the mech:

anisi'n illustrated in the accompanying drawy) ing, 1n which- Figure lis a perspective view of my de vice comprising a double coaster-slide.Fig. 2 is a vertical section longitudinally of one of the slides. Fig. 3shows a Jfragment or the slide and middle supporting post and thecasting inside elevation for attaching the post to the slide and foruniting' the two portions of the slide which are here joined together.Fig. is a section on the line 4 4 of 3 and Fig. o is a cross section orthe slide on the line 5-5 of Fig. Q.

like characters of reference indicate lilre parts throughout the severalviews of the drawings.

A platform 6 is elevated by tour posts i' to the height from which theslides 8 are to descend, and the posts 7 are continued above theplatform to aid in supportingl suitable guard-rails 9. l have shown twocoaster slides 8 descending from the platforni in two diametricallyopposite direc-- tions, but in many installations in practice, only oneslide is used.

A stairway l0, leads from the `ground to the top of the platform andslides and pro.

vides the means for reaching the platform preparatory to the use ot theslide. lt is provided with hand-rails' ll to avoid accidents and also toaid the climber. l have Specification of Letters Patent.

shown three hand-rails il in middle one dividing the stairs l .into tworuns for separate use girls respectively.

The slide 8 comprises a pair of risers 9, preferably of wood, whichextend 'the full length of the slide and are longitudinally sinuous toimpart the desired wave nievernent to the person coasting, and to checkhis speed and to land him in a com itortable sitting position at thelower end ot' the slide. A series of undulations which vary the speedoi' the coaster and give him a series of thrills, one at each quickeningof descent, is more enjoyable than a single glide. l

l, the and platform by boys and ward curves 13, i3 at the upper portionoi the slide and 'a longer downward curve 14. at its lower end, each or'said curves merging into the substantially equal upward curves 15, asshown. lhese upward curves tend to slacken the rate oi' travel of theperson coasting, whereas the descent into the downward curvesaccelerates it.

The lower downward curve lll is much `longer than the two downwardcurves higher up, and it terminates with sub stantially horizontalportion at the end of the slide, whereby the speed oi the coaster ischecked and he cornes to a stop there instead of being violentlydischarged.

rl`he two risers are connected at their lower curved edges by a sheet cismooth instal lll, which is nailed thereto and provides a smooth surfacedown which the coaster glides by direct co 3 therewith. r'liis instal isrein'iiorciul and supported by a wooden door 17 ot' preferably n'ig'uedand grooved boards placed transverzly or' the slide and nailed to thcrisers. Sho corners of the slide where the floor joins bound andreinforced by a sheet metal angle-stripv i8, which laps the jointsbetween the risers and flooring and underlaps the slide and is nailed ateach longitudinal edge as shown.

The lower end oli' the slide is supported above the ground by legs 2G.at a suitable height to enable a childls toet to reach. the ground bythe bend of his knees, when he arrives at the lower end of the slidewhen coasting1 down it.

About midway of the oit.' the slide provide a pair of post-supports 2l,and' it this location l also p f l' transversely into two 'thereforeshape the risers with two downtions :forconvenience in manufacture,stor- 1 age and transportation.' Dowel pins 22 enter the abutting endsof -the joint thus formed, and a plate 23 of cast iron overto receivethe end of post 2l. The post 21 is secured by a set screw.

In assembly, the platform 6 can be erected and the upper portion of theslide to and including the posts 21, placed. Then the lower portion oftheslide can be readily brought into position with the dowel pinsinserted and the joint closed by the aid of a bolt 24 passing through aperforated lug on plate 23 and through a screw-threaded hole in a lug 25in a plate bolted to the lower riser member, as shown in Fig. 3, andwhen the joint vis thus drawn tight the bolts securing the plate 23 tothe lower riser-memberA may be easily placed. The joint can be kepttight by the'aid of the bolt 24. l

The sheet metal iioor pover 16 is bent down against the edges of thefloor at the joint, as shown in dotted lines in Fig. 4, and there heldwhen the vends are drawn togathers The risers for the upper slide membercan be cutout of one piece of timber with security but size of the curvein the lower slide member requires the use of two pieces of timber tosecure the strength of the grain, and these I unite by a bevel scarfjoint 25. As the risers form hand-rests for the coasters I avoidsplinters by bending a capstrip of wood 26 and nailing it upon the upperedges of the risers.

The bases of the legs 20 andV posts 21 are embedded in concrete 27, inthe manner shown. 1,

' While I have described my invention with more or less minuteness asregards details of construction and arrangement' and as being embodiedin certain precise forms,

I do not desire to be limited thereto unduly or any more than is,pointed out in the claims. On the contrary, I contemplate all properchanges inform, construction and arrangement, the -omission ofimmaterial elements and' the substitution of equivalents ascircumstances may suggest or as necessity may render expedient.

1. A coaster slide having a plurality of downward curves and a pluralityof upward curves merging therewith, said slide comprising a pair ofsinuous risers and a smooth metal covered iioor connecting them, saidslide being in two transversely separable members, a socket plate boltedtoone member of the slide and havingv an extension overlapping the otherslide member, means fixed to said other slidesmember to engage saidplate and .draw said slide members together, and a post inthe socketsupporting the socket. plate.

2. A coaster slide having a plurality of downward curves and a pluralityof upward curves merging therewith, said slide comprising a pair ofsinuous risers and a smooth-floor connectingthem, said slide being intwo transversely separable members, ,dowel pins in their meeting ends, ametal plate bolted tothe outside of one member of the slide, said platehaving an under side post socket and a perforated lug on an 'extensionof the plate which overlaps the other slidemember, a second plate with aperforated lug bolted to the last named slide member, a bolt connectingthe two lugs to draw the slide members together, means -to secure theplate to said last slide member and a po'st to enter the socket in theplate and extend to the ground to support the slide at said joint.

In witness whereof, I have hereunto set my han'd and seal at Anderson,Indiana, 'this 8th day of July, A. D. one thousand nine hundred andsixteen.
